The present invention` is directed to the provision of an improved scale which'is particularly adapted for mixingand compounding purposes.

A further object of the present invention resides in vthe provision of a novel chart adapted for use in cooperation with a weighing scale7 which chart is provided with oneV or a number of fields preferably successively disposed in having weight indicating graduations designating the amounts of quantities and ingredients and also preferably having indicating data designating av subst-ance or ingredient which is represented ,by a particular weight field Vor fields. T he chartfurthermore may be provided Awith supplemental mixing instructions oi' other written information. Y V v For a.' clear and complete understanding of the objects andwadvantages of my improved construction of scale and ofthe chartsl for use in lconnection therewith reference may be made to the present practice in a household kitchen where various mixtures of food areconcocted. The present practice in a kitchen of the average household is to utilize cook books, receipt books ,or written receipts, measuring vessels and `appliances of various `sorts and conversion tables of comparatively rough ,acciiracy. Scales are utilized only `to a 'limited extent y as most receipts call in part for quantities of substances defined byvarious liquid measures. As a resultthe average housewife in l mixing a comparatively simple' mixture has `to utilize not only a large number of books, .tables and the.` like 'but also various conl taining vessels and ymeasuring vessels. Furthermore,` the housewife must be able -to interpolate various tables and convert liquid into dry'measure, etc.

By utilizing the scale and the mixing `chaits 'which form the subject matter of the present invention this procedure 'is materially simplified In-p/lace Vof utilizing cook books, written receipts and the like," the housewife may be providedl with a card index le containing anumber of supplemental charts or cards. An individual card or chart is provided for each receipt. This ychart or card -not only is provided with a Y list of the ingredients and instructions as to their use andmixing but also is provided with une oiluc'iie 'weight fields the le' er mixture on a weight basis. For convenience .the weight fields of the charts themselves are designated with 'theI particular ingredient lrepresented bythe .particular weightfield.

Furthermore, the order or sequence ofthe fields ion'the chart determines the orderin which ingredients are to be `added to the mixture.

receipt chart in a weighingscale of novel forni. After placing the mixing receptacle uponthe scale pan the weight of this receptacle is tared off `and the housewife then merely observes the `chart and adds the various ingredients in the `order called fcrby vthe chart. The ingredients are added in the order set forth on the chart and their quantity is readilydeterm'ined by the housewife observing the correlation ofthe indicating hand of the scale and the particular fields and designating graduations on the charts which relate ,to the particular ingredient being added to the mixing receptacle.V Inthis way .themixing procedure 'is materially sim- 'plificd7 theiise of large numbers of measurvingvessels is done` away with and coinpziratively complicated receipts can 'be 'made up with very great accuracy.

In ore detail the scaleto which my invention is shown as here applied is of the conventional fan type. tcomprises a base TI Q having"` the usual scale heath supported i Thekhousewife after selecting a l -desir-ed receipt, say, that of a cake, frointhe card .file placesthe card or supplementary thereon with a platform or platter 12. 13 is a tare beam and poise arrangement which can be used for taring ofi' the Weight of a receptacle such as 14. 15 is the indicator of the scale which is controlled by the auto-V matic counterbalancing mechanism 16. The chart housing 17 is of the general form used in scales of this type and is arranged to` cilitates the introduction of the cards into the chart housing. The cards upon vwhich the various receipts andvdirections are printed are shoivn m front view in Fig. 2. These cards preferably compriseV a central card portion 20 and a rim portion 21, the rim yportion being inthe form of .a beading which stiffens the edges of the cards and prevents the abrasion and mutilation of the same. The rim portion further serves to cooperate With guiding slots 22 (see Fig. 4i), Which guiding slots are preferably disposed in bracket members 23 xed to the chart. housing. The arrangement of the guide slots QQ is such that vthe inserted cards 20 with their rim portions 21 pass back ot and clear of the indicator 15 so that this indicator can freely traverse the .supplementary chart 20 when theA same is in position in the scale. The usey of the device Will be obvious. Assume that it is desiredA to mix a particular sponge cake. The user of the appliance turns to a card file and selects the desired card giving the receipt for the particular cake mixture which is intended to be made. This receipt card is then .inserted in the scale. In addition to providing `Written directions as to the method ot compounding the receipt the receipt card carries a graduation line 26 with a number of graduations such as 27 thereon. The first operation is to adjust the tare poise 13 to tare off' the receptacle. rlhe indicator now is at zero at the zero graduation on the chart 20. The user first adds beaten eggs to the receptacle 14 until the indicator stands at the right hand Vgraduation. adjacent the beaten eggs7V designation on the chart. Following this granulated sugar isl added 'until the granulated sugar field on the' chart is traversed by the indicator. The operator then observes that the next ingredient symbol is not Written out but is merely an initial.V By reference to the chart this symbol O is ascertained to call for orange juice. Orange juice is then added until the indicator has traversed this particular field. The

The supplemental chart 2O which carries the successive Weight fields Which are delimitated by the graduations 9.7 is preferably located in the chart housing byv a suitable stop or abutment member .30. yThe location of this abutment member is such that the zero graduation of the supplementary chart is disposed in alignment with the Zero point of thefixed Weight chart when the supplementary chart or card is pushed in tor its Lfullest extent so as to abut against part 30.

VJhile l have described the present invention particularly ivith respect to its use in a household it Will be understood that the device also finds application. in commercial uses Where there is a mixing or compounding of any substances or ingredients. F or example the 'device may be utilized for secret compounding inasmuch as the supplemental charts ot themselves do not bear any, direct Weight indications. For secret compounding the fixed Weight chart preferably Would be done aivay vvith. Also rthe tare graduations Would Vbe dispensed with and preferably afixed tare arrangement Would be provided. vThe user of the device would then be unable to tell the Weight equivalents of the ingredients of the mixture being compounded.

Other modifications and uses of the device herein disclosed Will readily be apparent to those skilled in the art.
